Special Cases In Μw/Cm²; Rereading Programs; Using Probes - Chauvin Arnoux C.A 43 FILEDMETER Mode D'emploi

When the digit furthest to the left is active, press to display three hyphens and
the previously displayed value disappears. Idem for the button when the active
digit is located on the far right of the display.
Note :
The increase of the digit on the left gives access to tens by carrying the remainder. The
validation of "- - -" allows you to block the current programming which will no longer appear
on the display in measurement mode. To do this, simply return to measurement mode by
pressing when these symbols are displayed.
PRGM
SPECIAL CASE OF µW/cm²
The programming of alarms in the case of µW/cm² measurements is distinguished by the
possibility of suppressing or setting the decimal point (whole number or decimal number).
To suppress the decimal point, activate the digit on the right (see previous paragraph "Writing
a number"), press again to suppress the decimal point.
To set the decimal point (only one decimal possible), activate the digit on the left then press
again. The decimal point appears again.
RE-READING PROGRAMS
To re-read the information contained in the program memory you must, for each unit, call up
the programming by pressing the button, then scroll each value by pressing the
PRGM
different function buttons. The digital display then indicates the values contained in the
memory, with the function symbol displayed.
In all cases, changing from programming mode to measurement mode by pressing PRGM or
changing programming function, will validate all the values present in the memory at this time.

USING PROBES

The measurement of an electric field works on the same principle as an aerial which picks
up a radioelectric signal. The sensitive part of the aerial is a detection cell with a very low
threshold.
This DC signal resulting from the detection is transmitted to the measurement instrument by
a resistive line ensuring maximum transparency that does not disturb the electrical field in
which the instrument and its aerial is immersed.
